Abstract: Methods and systems for determining switch assignment within wireless communication regions served by plural telecommunication equipment. Telecommunication switch borders may be re-defined based on system use patterns and data. Cellular antennas and/or base stations may be reassigned to switches based on use data. A region comprising a plurality of switches and cell sites in need of border optimization may be identified (401). Cell traffic statistical data collected 402 for cellular sites may be utilized in the analysis (403). Latitude and longitude information for each cell being studied may be identified (402) and used. Contours defining an optimized region are generated (404) using the statistical and/or lat/long information for equipment. Switches, cellular antennas and/or base stations may be reassigned based on the optimized region.

Abstract: A device provided in a mobile phone for notifying the user of the receiving of a call signal, includes a vibrator having a rotor mounted in the body of the mobile phone to make a vibration tangibly sensed by the user when the call signal is received by the mobile phone, a battery pack detachably attached to the body to supply power to the mobile phone, and a protrusion formed on the outer surface of the battery pack at the weight center of the mobile phone. Thus, the mobile phone placed on a surface is rotated about the protrusion upon receiving the call signal.
